Japanese Patent Laid-Open No. 10-194317

However, since the stopper member is provided separately from the apparatus main body, the conventional technique has a problem that the stopper member cannot be provided with a virgin mechanism for displaying unauthorized use.
SUMMARY An advantage of some aspects of the invention is to provide a discharge device in which a stopper member is provided with a virgin function.

In order to solve the above-mentioned problem, the present invention attaches the mounting cylinder 20 to the container body neck portion 2 and moves the operating member 30 standing from the cylinder member 10 hanging down into the container body to the mounting cylinder top wall 22. In the discharge device in which the push-down head 40 is mounted on the upper part of the operating member, the penetrating head is vertically movable,
The guide member 23 surrounding the actuating member 30 is erected from the mounting tube top wall 22 and the stopper member 50 is provided with a stopper portion 52 extending through a connecting portion 51 provided at the lower part of the outer peripheral surface of the pressing head 40. Integrally molded to the pressing head 40,

The connecting portion 51 is provided so that it can be broken by pulling the stopper portion 52 rearward at the blocking position, and can be displayed for unauthorized use, and the stopper member after the connecting portion 51 is broken. 50 is provided so as to be fitted to the guide tube 23.

Further, according to the present invention, the connecting portion 51 is formed of a rod-like or thin strip-shaped easy-to-break material, and the vertical position of the connecting portion and the length of the connecting portion in the front-rear direction are arbitrarily set. Thus, the extending dimension of the connecting portion is provided so as to be set to an arbitrary value.

  Furthermore, the present invention is characterized in that the connecting portion 51 is composed of a pair of left and right easily breakable materials.

In the present invention, the guide cylinder is raised from the top wall of the mounting cylinder and the stopper member is formed in a C-shaped cross section of the rear opening that can be fitted to the rear surface of the guide cylinder. Further, the stopper member can be provided with a function of preventing the pressing head from being pressed down.

It is a partially cutaway side view according to the present invention. It is a top view of a stopper member. It is action explanatory drawing which shows the blocking position of a stopper member. It is action | operation explanatory drawing which shows the state which the stopper member separated and fractured | ruptured from the pressing-down head.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a container body, and the mouth-and-neck portion 2 stands up through a shoulder portion.
Reference numeral 10 denotes a cylinder member, and an outward flange (not shown) attached to the upper end of the peripheral wall 11 is engaged with the upper end of the container body neck to suspend the peripheral wall 11 into the container body 1.

  Reference numeral 20 denotes a mounting cylinder, which screwes the peripheral wall 21 to the outer surface of the container body mouth and neck, and presses the outward flange of the cylinder peripheral wall 11 to the upper end of the container body mouth and neck by an inward flange-like top wall 22 on the upper surface of the peripheral wall 21. Further, the guide tube 23 is erected from the inward flange-shaped top wall 22. The guide tube may be provided integrally with the mounting tube 20 or may be provided separately.

  Reference numeral 30 denotes an operating member, and a stem 31 erected from a known cylindrical piston fitted into the cylinder member 10 so as to be movable up and down is moved up and down into the guide cylinder 23 through the through-hole of the inward flange-shaped top wall 22. Insert freely.

  Reference numeral 40 denotes a pressing head which hangs the inner and outer double cylinders 42 and 43 from the top wall 41 to fit the inner cylinder 42 to the upper end of the stem 31 and to move the outer cylinder 43 up and down to the outer surface of the upper end of the guide cylinder 23. A nozzle 44 that is movably inserted and communicates with the stem 31 is provided to project forward from the outer peripheral wall 43.

  Reference numeral 50 denotes a stopper member. As shown in FIG. 2, the stopper portion 52 is integrally formed on the outer peripheral wall 43 through a connecting portion 51 that protrudes rearward from the rear lower end of the outer peripheral wall 43 of the pressing head 40. .

  The connecting portion 51 is made of a rod-like or narrow strip-like breakable material, and is formed as a pair on the left and right. The number of easily breakable materials is preferably a pair, but is not limited to this number. The pair was selected in consideration of sufficient strength to support the stopper member 50 and ease of breakage described later.

  The stopper portion 52 has a C-shaped or semicircular cross-sectional shape and is formed so as to be fitted to the guide tube 23. The upper end of the stopper portion 52 is preferably formed in an upwardly convex arc shape for the reason described later, and the left and right portions of the stopper portion 52 are preferably formed in the cutout portion 53 from the viewpoint of reducing the amount of resin. In addition, the finger hooks 54 are projected from the lower end of the front portion of the stopper portion 52 to the left and right.

Next, the operation will be described.
FIG. 1 shows a state at the time of molding. The connecting portion 51 supports the stopper member 50 in a horizontal state. Discharging is performed by pressing down the pressing head 40. In order to prevent inadvertent pressing of the pressing head, the stopper member 50 is pressed down, rotated forward, and reversed (turned 180 degrees), thereby lowering the lower end surface of the pressing head 40 and the mounting cylinder top wall 22. It suffices to fit between the upper surface and the rear surface of the guide tube 23 (this fitting position is the blocking position of the stopper member 50).

When the stopper member 50 is rotated by being pushed down, the stopper member 50 slides on the upper surface of the inward flange-like top wall 22 of the mounting cylinder 20, but the upper end of the stopper portion 52 is formed in an arc shape as described above. Therefore, the fitting between the pressing head 40 and the mounting cylinder 20 is smoothly performed.

In the present invention, since there is one significance in providing the stopper member 50 with the virgin function, the connecting portion 51 is extended when the stopper member 50 is pushed down, and the stopper member 50 is connected at the blocking position. It is necessary for the portion 51 to be able to be broken by pulling the stopper portion 52 fitted to the rear surface of the guide tube 23 backward .

This is because the extension dimension of the connecting portion 51 is set to an arbitrary value by appropriately setting the vertical position of the connecting portion 51 and the length of the connecting portion in the front-rear direction, and the blocking position of the stopper member 50. Then, the connection part 51 is achieved by making it possible to break by pulling the stopper part 52 backward. Further, by defining the connecting portion 51 as described above, the fitting of the stopper member 50 with respect to the distance between the pressing head 40 and the mounting cylinder 20 can be arbitrarily set between a loose state and a hard state.

In order to discharge, the stopper portion 52 may be pulled rearward as shown in FIG. 4, and then the connecting portion 51 is broken, so that the stopper member 50 is moved from between the guide tube 23 and the pressing head 40 and the mounting tube 20. It can be separated backwards. After discharging, the stopper member 50 is fitted between the push-down head 40 and the mounting cylinder 20 and is fitted into the guide cylinder 23, so that it can be used as a stopper when not in use.

  The present invention can be used in the field of a discharge container provided with a pump-type pressing head.
